What l claim is:

l. An automatic regulator for the height of a `vater level comprising a fiow obstructing member, means for pivotally mountingr said member at its lower edge, and means for normally maintaining said member in a position inclined in the direction opposed to the direction of flow of the Water, said member being capable of moving from said position to a horizontal collapsed position with the direction of flow, said last named means 'comprising a Weight and pulley mechanism and tension means attached to the said member passed over said pulley and attached to the said weight, the said pulley being placed over and in line with the normal position of the said member, whereby the torque exerted by said mechanismen said member increases to a maximum and decreases during the to its collapsed position.

2. An automatic regulator for the height of a Water level comprising a' How obstrucfrom its normal momen ting member, means for maintaining said member in a position inclined to the direction of How of the Water, and means for supporting said member in a collapsed position,

said member being capable of assuming any intermediate position, said rst mentioned means exerting a torque on said member, which reaches its maximum at an intermediate position of the member.

3. ln an automatic regulator for the height of a Water level, a flow obstructing member7 means for pivotally mounting said member at its lower edge, pulley and Weight mechanism for exerting a turning moment on said member and for normally maintaining said member in a position inclined in the direction ot'low ot' the Water, one of the pulleys ol said mechanism being placed ,in line with and over the normal position of said member, and tension means attached to the said mem ber, passed over the said pulley and attached to the weight, whereby a maximum moment is created on said member when the same is in its vertical position.

In testimony whereof I have ailixcd my signature to thisspecifieation.
